2002 - Maximum Product of the Length of Two Palindromic Subsequences\. Medium Given a string `s`, find two **disjoint palindromic subsequences** of `s` such that the **product** of their lengths is **maximized**. The two subsequences are **disjoint** if they do not both pick a character at the same index. Return _the **maximum** possible **product** of the lengths of the two palindromic subsequences_. A **subsequence** is a string that can be derived from another string by deleting some or no characters without changing the order of the remaining characters. A string is **palindromic** if it reads the same forward and backward. **Example 1:**  **Input:** s = "leetcodecom" **Output:** 9 **Explanation:** An optimal solution is to choose "ete" for the 1^st subsequence and "cdc" for the 2^nd subsequence. The product of their lengths is: 3 \* 3 = 9. **Example 2:** **Input:** s = "bb" **Output:** 1 **Explanation:** An optimal solution is to choose "b" (the first character) for the 1^st subsequence and "b" (the second character) for the 2^nd subsequence. The product of their lengths is: 1 \* 1 = 1. **Example 3:** **Input:** s = "accbcaxxcxx" **Output:** 25 **Explanation:** An optimal solution is to choose "accca" for the 1^st subsequence and "xxcxx" for the 2^nd subsequence. The product of their lengths is: 5 \* 5 = 25. **Constraints:** * `2 <= s.length <= 12` * `s` consists of lowercase English letters only.
